Description

DESCRIPTION

Dishwasher washing basket

The present invention relates to a washing basket according to the preamble of claim 1 of the patent.

Apart from that, the invention also relates to an arrangement with a dishwasher and a washing basket as well as to a method for washing objects, arranged in the basket interior space of a washing basket, in a dishwasher.

In the case of the state of the art, generic type washing baskets are used for washing crockery, glasses, cutlery and the like in dishwashers. Especially in the industrial sector, such washing baskets can also be used for washing other items in a dishwasher.

A washing basket with a grid-shaped basket base and side walls has been shown, for example, in EP 1287780 B1.

US 1,285,490 A, JP 11-42196 A and US 3,009,579 A show washing baskets with elongated base members running in a curved manner. In the case of document EP 1287 780 B1, some of the elongated base members configure a grid-like structure. US 2,035,625 A shows a washing basket of the generic type.

The object of the invention is to improve washing baskets of the generic type in that they contribute to the best possible washing result and are suitable for automated transport through a dishwasher. For this, the invention proposes a washing basket according to claim 1 of the patent.

Through the at least partly curved elongated base members, the washing liquid, sprayed into the washing basket from below in the dishwasher, is selectively deflected, so that the objects to be washed, stored in the inner basket space, are subjected to the washing liquid from as many different sides as possible.

Hereby, it is avoided at least for the most part that there are areas of the objects to be washed that are not subjected to the washing liquid. Overall, therefore, the washing result is improved through the elongated base members which run in a curved manner at least in part. The washing baskets according to the invention can be used for washing crockery, glasses, cutlery, but also other objects in correspondingly suitable dishwashers. Correspondingly, the washing baskets according to the invention can be used both in the catering sector and in industrial production.

For automated transport through a dishwasher, configuration forms according to the invention of washing baskets provide that the basket base, seen in the top view of the basket base, additionally has a cross-shaped structure that it runs through the center point of the basket base, from elongated base members which run in each case parallel to one of the side walls of the washing basket. In this regard, the elongated base members forming the cross-shaped structure favorably reach further downward, that is, in the direction away from the basket interior space of the basket base, than the others. elongate base members of the basket base, such that known dishwasher clamps can engage the cross-shaped structure to transport the wash basket through the dishwasher.

In the case of the invention, it is possible that the cross-shaped structure subdivides the basket base into, preferably four, segments arranged separately from one another by means of the cross-shaped structure, and that the members elongated base elements that run in a curved manner are arranged exclusively on the segments. Additionally, but also as an alternative, provision can also be made for the cross-shaped structure to be arranged on the side of the curvedly running elongated base members opposite the inner basket space. In this regard, as stated above, the elongated base members of the cross-shaped structure are preferably provided to protrude beyond the other elongated base members in the direction away from the basket interior space.

The basket interior space surrounded by the basket base and the side walls may be open upwards, ie on the opposite side to the basket base. However, the washing baskets according to the invention can also be equipped with lids or the like, optionally in the form of a grid.

In principle, the washing baskets can be made of different materials. Preferably, it is a plastic washing basket. The elongated base members and side walls, preferably the entire wash basket, may or may be configured in one piece. The washing baskets according to the invention can be manufactured, for example, by injection moulding.

In case of doubt, the terms up and down refer to an operating position of the wash basket in which the basket base forms the lower closure of the wash basket and, as a rule, is located on a horizontal bottom. . Viewed in this operating position, the vertical extent of the elongated base members is favorably greater, preferably at least two or at least three times greater than the width or, in other words, the horizontal extent of the elongated members. base.

The term basket base in the form of a grid describes that the basket base has free spaces or passage openings between the elongated members of the base, through which, for example, the washing liquid can enter towards the basket interior space through basket base.

Seen in top view of the washing basket, the washing basket can have, as is known per se, a rectangular, in particular square, basic shape, but also differently. The term rectangular or square basic shape also includes those configuration shapes in which the corners of this basic shape are rounded.

Especially preferably, it is provided that the part of the elongated base members, seen in the top view of the basket base, is configured in a curved way in sections or completely around the center point of the basket base.

In the case of the invention, the elongated base members can in principle be designed in such a way that they run curved quite differently. The degree of the curvature can also vary along the elongated base members.

However, especially preferred embodiments of the invention provide that the part of the elongated base members, seen in the top view of the basket base, running circularly or at least curved in the shape of a segment of a circle, it is preferably configured as a succession of elongated base members running in a circular manner or at least curved in the form of a segment of a circle. In this regard, at least some of the elongated base members, which run circularly or at least curved in the shape of a segment of a circle, seen in the top view of the basket base, have a common center of the circle. In particularly preferred embodiments of the invention, this applies to all elongated base members which run circularly or at least curved in the form of a segment of a circle, since they all have a common center of the circle. In this regard, the preferred variants provide that the common circle center or the common circle centers, seen in the top view of the basket base, is/are arranged on a diagonal of the basket base. In particular, if all, seen in the aforementioned top view of the basket base, the elongated base members running circularly or at least curved in the form of a circle segment have the same common circle center, this circle center it is favorably located at the center point of the basket base. The radii of curvature of the elongated base members which run preferably circularly or at least curved in the shape of a segment of a circle increase, in preferred embodiments of the invention, seen in the mentioned top view of the basket base, from favorably with the distance from the center point of the basket base and/or from its center of the common circle.

In addition to the washing basket itself, the invention also relates to an arrangement with a dishwasher and a washing basket according to the invention, the washing basket being arranged in the dishwasher and the washing liquid nozzles being arranged of the dishwasher below the basket base, and a respective washing liquid discharge direction of the respective washing liquid nozzles being directed towards the basket base. In this connection, provision is preferably made for the washing liquid nozzles to be arranged in or on a rotatably mounted washing arm of the dishwasher, the washing arm then also being located below the basket base. In the case of this arrangement, the washing liquid is sprayed from the washing liquid nozzles from below through the basket base onto the objects to be washed into the interior space of the basket. In this connection, a relatively large percentage of the washing liquid discharged as a whole by the washing liquid nozzles passes through the free spaces or passage openings in the basket base without being diverted in this respect. However, if the washing liquid reaches the elongated base members running in a curved manner, then it is diverted there, so that a plurality of different directions are formed in the inner space of the basket, between which the washing liquid reaches the objects to be washed and stored in the interior space of the basket. Thus, as explained at the beginning, a particularly good washing result is achieved.

Additionally, the invention also relates to a method for washing objects, arranged in the interior basket space of a washing basket according to the invention, in a dishwasher, the washing basket being arranged for washing the objects in the dishwasher above the washing liquid nozzles of the dishwasher, and washing liquid being sprayed from the washing liquid nozzles through the basket base into the basket interior space, portions of the washing liquid being diverted by the elongated members of base that run in a curved way towards the interior space of the basket.

In the case of the objects to be washed arranged in the basket interior space, crockery, glasses, cutlery, but also other objects can be treated, as already mentioned above.

Additional features and details of preferred embodiments of the invention are explained in the following description of the figures. They show:

FIGS. 1 to 3 are representations of a first exemplary embodiment of a washing basket according to the invention;

FIGS. 4 to 6 are representations of a second exemplary embodiment of a washing basket according to the invention, and FIGS.

Fig. 7 a schematic representation of the arrangement of a washing basket according to the invention according to the first exemplary embodiment in a dishwasher in a section along section line A-A in Fig. 3.

Figure 1 shows, in a perspective view obliquely from above, a washing basket 1, in which a part of the elongated base members 3 are configured to run in a curved manner according to the invention. The washing basket 1 has a basket base 6 in the form of a grid, formed by the elongated base members 3, 4, 5, and side walls 7. The side walls 7 and the basket base 6 together surround the interior space of basket 8 of the washing basket 1. As shown in this embodiment, the side walls 7 may be perforated by areas with openings. The inner basket space 8 is open at the top in this exemplary embodiment. In the normal operating position of the wash rack 1, shown in FIG. 7, it is generally in a horizontal plane.

The washing baskets 1 shown here each have a basic square shape with rounded corners. However, as already explained at the beginning, the washing baskets 1 according to the invention can, of course, also be designed with rectangular shapes or other basic shapes, optionally with rounded or even non-rounded corners. Favorably, the washing baskets 1 according to the invention are made of plastic. In this connection, provision can be made for all components of the washing basket to be connected to one another in one piece. However, multi-piece variants are also possible. The washing baskets 1 according to the invention can be produced, for example, by injection molding.

Figures 2 and 3 show the first embodiment of the washing basket 1 according to the invention in a top view of the basket base 6. In Figure 3, the washing arm 15 is additionally shown, mounted rotary, of a dishwasher 2, which has the washing liquid nozzles 14 and sprays this washing liquid 18 from below through the basket base 6 into the interior of the basket base 8. The axis of rotation around which the wash arm 15 rotates during the operation of the dishwasher 2 is favorably located more or less directly below the central point 9 of the wash basket 1 during the washing process.

Observing the top views according to figures 2 and 3 of this first embodiment, it can then be clearly seen that a part of the elongated base members, in this case in the form of elongated base members 3, are configured running from curved manner according to the invention in the top view of the basket base 6. In each case, it is a succession of elongated base members 3 that run in a curved manner. The elongated base members 3, seen in the top view shown, are configured in a curved manner in sections around the center point 9 of the basket base 6. In this first embodiment, the elongated base members 3 are configured to run curved in the shape of a segment of a circle.

However, additionally, the basket base 6 also has elongated base members 4, which run parallel to in each case one of the side walls 7. In this embodiment, some of these elongated base members 4 form the cross-shaped structure 12, which is particularly visible in Figures 2 and 3. This cross-shaped structure 12 or the elongated base members 4 that form it offer a corresponding gripper of a dishwasher conveyor 2 a surface of attack, so that the gripper can grab the washing basket 1 in one of the elongated base members of the cross-shaped structure 12 and drag it through the dishwasher 2 during the washing process. For this, the elongated base members 4 favorably protrude over the other elongated basket base members 3 and 5 towards the lower side away from the inner basket space 8.

In this first example of embodiment, the cross-shaped structure 12 on the basket base 6 subdivides the basket base 6 into four segments 13, arranged separately from each other, being arranged in each of these segments 13 in each case elongated base members 3 running in a curved manner. The elongated base members 3 are configured to run arcuately in each case in the form of a segment of a circle. The elongated base members 3 arranged in a respective segment 13 have in each case a common circle center 10. Within the respective segment 13, the greater the distance of the respective elongated base member 3 running in the form of a segment of a circle from the respective center of the circle 10, the greater the radius of this elongated base member 3. The centers of the circle 10 of the four segments 13 lie in each case on a diagonal 11 of the basket base 6.

In order to stiffen the basket base 6 in the area of the elongated base members 3 which run in a curved manner, in preferred embodiments, such as those shown here, all or some of the members are additionally provided. elongated base members 5 connecting the curved elongated base members 3 to each other, which, as shown here, are arranged to run radially favorably with respect to the respective center of the circle 10 common.

While in this first example of embodiment according to figures 1 to 3, the elongated base members 3 that run in a curved manner in the segments 13, separated from each other by the cross-shaped structure 12, of the basket base 6 are curved in each case in the form of a segment of a circle, in the second embodiment of the invention according to FIGS. 4 to 6 it is provided that at least some of the elongated base members 3, seen again in the top view according to figures 5 and 6, they are configured in a completely circular shape. All the elongated base members 3, made in a curved manner in the aforementioned top view in this second embodiment, have in this embodiment a common center of the circle 10, which coincides with the center point 9 of the base of basket 6 in this example of embodiment. Also in this case, the radii of curvature of the elongated base members 3 which run curvedly in the shape of a circle, seen in the top view of the basket base 6, increase with the distance from the center point 9 of the base of basket 6 and thus also in this exemplary embodiment from their common circle center 10. In the top views according to figures 5 and 6 it can be clearly seen that in this second example of embodiment of washing baskets 1 according to the invention a cross-shaped structure 12 is also present, formed by elongated base members 4 which run parallel in each case to one of the side walls 7, which, as in the case of the first exemplary embodiment already illustrated, serves to be able to transport the washing basket 1 through a dishwasher 2 in one direction. mechanically actuated way. However, unlike the first embodiment, this cross-shaped structure 12 in this second embodiment does not separate the basket base 6 into four segments 13, on which in each case elongated base members 3 are provided. in the form of a segment of a circle. In this second exemplary embodiment, it is rather provided that the elongated base members 4 forming the circular structure 12 are arranged exclusively on the side of the elongated base members 3 that extend in a curved manner opposite the interior space of the basket 8.

Also in this second exemplary embodiment, elongated base members 5 arranged radially with respect to the center of the common circle 10 are provided, which connect the elongated base members 3 running in a curved manner to each other and thus stabilize even more the basket base 6.

The wall thicknesses of the elongated base members 3, 4, 5 may generally be, for example, in the range of 1 mm to 10 mm, preferably 2.5 mm to 4 mm.

FIG. 7 shows, by way of example, an arrangement with a dishwasher 2 and a washing rack 1 according to the invention arranged therein, the dishwasher 2 being shown only in a highly simplified manner. The dishwasher 2 can be designed as is known per se in the state of the art. Figure 7 shows a vertical section through this arrangement along section line AA drawn in Figure 3. In the shown operating position, the washing basket 1 rests on the corresponding rails 19 of the dishwasher 2. Therefore, in figure 7 the operating position of the washing basket 1 is shown, in which the washing process in the dishwasher 2 is carried out. In this operating position, the washing basket 1 is mounted horizontally in the dishwasher 2. In the interior space of the basket 8, in figure 7 are illustrated in a very schematic way glasses represented in section as objects 17 to be washed. The washing liquid nozzles 14, which in the exemplary embodiment shown here are formed on the rotatably mounted washing arm 15 of the dishwasher 2, are located below the basket base 6. The discharge directions of the washing liquid 16 from the respective washing liquid nozzle 14 are directed towards the basket base 6, so that the washing liquid 18 during the washing process reaches from below through the basket base 6 in the form of grid towards the inner space of the basket 8 in order to wash there the objects 17 to be washed. Thus, a method according to the invention is shown for washing objects 17, arranged in the basket interior space 8 of a washing basket 1 according to the invention, in the dishwasher 2, the washing basket being arranged 1 for washing objects 17 in the dishwasher 2 above the washing liquid nozzles 14 of the dishwasher 2, and washing liquid 18 being sprayed from the washing liquid nozzles 14 through the basket base 6 into the space interior of basket 8, parts of the washing liquid 18 being diverted by the base webs 3 that run in a curved manner towards the interior space of basket 8. Other parts of the washing liquid 18, which do not reach the elongated base members 3 at penetrate the basket base 6, they reach the inner space of basket 8 without deviation. Overall, it is thereby achieved that the objects 17 to be washed, arranged in the interior space of the basket 8, are reached by the washing liquid 18 from different directions, which as a whole leads to a very good washing result. Okay.
